2021 Marathon Course


The route for the 2021 Marathon will change slightly based on recent requests by the police and Riverfront Wilmington.  The route will continue to include much of the significant route updates that occurred in 2019, with a few minor adjustments. 

The marathon course will continue to run through some of the most scenic parts of downtown Wilmington and the routes unify the full, half and team relay courses so everyone uses the same routes for the first 13 miles.  The 2nd half of the full marathon course will continue to run along the recently completed Jack Markell Trail to New Castle Elementary School and back.  The trail offers some amazing scenery and will be stocked with 3 water stops and port-a-pots where access permits. 


Adjustments and changes might be made to the 2021 Full Marathon Course.


The course will consist of 14 water stops including 2 that you will pass in each in each direction on the Markell Trail and one at the turnaround at New Castle Elementary School.  Due to limited access points on the trail, we will offer full bottles of water at the stop at Mile 14.5, just at the mouth of the trail entrance.  This will allow marathon runners to carry a full bottle to supplement their hydration while on the trail.  Feel free to bring your own hydration system (such as a camelbak) if you prefer or to refill your bottle at the other water stations along the trail.

Each water station will also offer port-a-pots for runner use.  On the trail, where you will pass them in each direction we will offer additional units to alleviate congestion.

We will provide complementary HUMA Gel, the official race gel of the Delaware Running Festival at one location on the marathon course. TRY ‘EM BEFORE RACE DAY.  FREE SAMPLE PACK.
